What is the range of distance from a heat source for an intermediate temperature sprinkler near a kitchen range top?

The correct answer identifies a range of 9 to 18 inches for the distance of an intermediate temperature sprinkler near a kitchen range top. This range is established based on safety protocols and guidelines for fire protection systems, especially in areas where cooking activities generate significant heat.

Intermediate temperature sprinklers are designed to activate at a specific temperature, typically higher than standard sprinklers, making them suitable for environments with elevated temperatures such as kitchens. The spacing is critical because if the sprinkler is too far from the heat source, it may not respond in a timely manner to control a fire, thus compromising safety.

In a kitchen setting, the proximity of the sprinkler ensures that it can detect the heat produced from cooking appliances effectively. By maintaining a distance within the specified range, it supports the prompt activation needed to extinguish potential fires before they escalate.

The options reflecting distances greater than 18 inches would not be appropriate as the increased distance could delay activation, increasing the risk of a fire spreading. Hence, the range of 9 to 18 inches is specifically tailored for optimal response in high-heat areas.
